OBJECTIVE: To investigate the clinical effect on functional dyspepsia differentiated as liver-stomach disharmony treated with acupoint application of Chinese herbal medicine and wax therapy on the basis of Professor TIAN Conghuo's theory, "regulating qi movement". METHODS: A total of 120 patients with functional dyspepsia of liver-stomach disharmony were randomly assigned to a combined therapy group (30 cases, 1 case dropped out), an acupoint application group (30 cases, 1 case dropped out), a wax therapy group (30 cases, 1 case dropped out) and a basic therapy group (30 cases, 2 cases dropped out). In the basic therapy group, omeprazole magnesium enteric-coated tablets were administered orally, 20 mg each time, once daily. Besides the treatment as the basic therapy group, the Chinese herbal acupoint application was used at Zhongwan (CV12) and Shenque (CV8) in the acupoint application group, and remained for 4 h in each intervention; and in the wax therapy group, wax therapy was delivered at the sites of Zhongwan (CV12) and Shenque (CV8) of the abdominal region and remained for 20 min in each intervention; and in the combined therapy group, the acupoint application was combined with wax therapy, administered once every other day or every two days, 3 times weekly. The duration of treatment was 4 weeks in the four groups. Before and after treatment, the score of main symptoms, the score of 36-item short-form health survey (SF-36) and the score of liver-stomach disharmony pattern were observed; and the clinical effect was evaluated in the four groups. RESULTS: After treatment, regarding main symptoms and liver-stomach disharmony pattern, the score of every item was lower than that before treatment in the 4 groups (P<0.01). The score for each dimension in SF-36 was higher than that before treatment in the combined therapy group and the acupoint application group (P<0.01, P<0.05). In the wax therapy group, the scores for physiological activities, bodily pain, general health, vitality, social activities and mental health in SF-36 were higher than those before treatment (P<0.01, P<0.05). In the basic therapy group, the scores for physiological performance, bodily pain, general health and mental health in SF-36 were higher than those before treatment (P<0.05, P<0.01). After treatment, in the combined therapy group, the score for gastric distension and discomforts was lower than those of the basic therapy group and the wax therapy group (P<0.01), and the scores for gastric fullness in the morning, pain in the upper abdominal region and burning sensation in the upper abdominal region, as well as the score for liver-stomach disharmony pattern were lower than those in the rest 3 groups (P<0.01, P<0.05). In the combined therapy group, the scores for physiological activities, physiological performance, and bodily pain were higher than those of the basic therapy group (P<0.01, P<0.05), the scores for physiological activities and bodily pain were higher when compared with those in the acupoint application group (P<0.01, P<0.05) and the scores for physiological activities and vitality were higher when compared with those in the wax therapy group (P<0.05). After treatment, the score for each item of main symptoms, the score for liver-stomach disharmony pattern in the acupoint application group, and the score for liver-stomach disharmony pattern in the wax therapy group were all lower in comparison with those in the basic therapy group (P<0.01, P<0.05). The total effective rates was 93.3% (28/30), 73.3% (22/30), 66.7% (20/30) and 50.0% (15/30) in the combined therapy group, the acupoint application group, the wax therapy group and the basic therapy group, respectively; and the total effective rate in the combined therapy group was superior to the other 3 groups (P<0.01); the total effective rates in the acupoint application group and the wax therapy group were higher than that in the basic therapy group (P<0.01). CONCLUSION The combination of acupoint application with Chinese herbal medicine and wax therapy, based on Professor TIAN Conghuo's theory of "regulating qi movement", can effectively treat functional dyspepsia, alleviate main symptoms and improve the quality of life in the patients.

OBJECTIVE: To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents. METHODS: This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs). RESULTS: This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed. CONCLUSION STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

AIM:To compare the differences, correlations and consistency of IOL Master 700 or Lenstar LS900 in preoperative ocular biometry and the accuracy of intraocular lens(IOL)degree calculation of cataract patients with high myopia.METHODS: Retrospective study. A total of 136 cases(136 eyes)of high myopia and cataract patients who underwent phacoemulsification at the ophthalmology department of Army Medical Center of PLA from March 2021 to March 2023 were collected, with a mean age of 57.38±8.08 years. Patients were divided into 3 groups based on axial length(AL): 41 eyes in group A(26 mm≤ AL ≤28 mm), 43 eyes in group B(28 mm< AL ≤30 mm)and 52 eyes in group C(AL >30 mm). AL, mean keratometry(Km), anterior chamber depth(ACD), lens thickness(LT)and white-to-white(WTW)were preoperatively measured by two instruments, respectively. Barrett Universal II formula was used to calculate the IOL degrees of all patients, the appropriate reserved diopter was decided individually, and the prediction error(PE)and absolute error(AE)of the two instruments were compared.RESULTS:The AL and ACD of patients in the three groups measured by Lenstar LS900 were higher than the AL measurd by IOL Master 700(all P<0.05), with a difference of AL measured by the two devices: group C>group B>group A. However, there was no statistical significance in LT, Km, and WTW measured by the two instruments(all P>0.05). All biometric parameters measured by the two devices were positively correlated(all r>0.9, P<0.05), and consistent(95% LoA of all groups were narrow). There was no statistically significant difference in AE calculated by the two devices(P>0.05), but the IOL Master 700 calculated a smaller PE than Lenstar LS900(P<0.05), with lower percentage of hyperopic shift in IOL Master 700.CONCLUSION:In cataract patients with high myopia, AL measured by Lenstar LS900 is longer than that by IOL Master 700, and the differences of AL increase along with the growth of AL. Both devices have a good prediction for IOL calculation, but IOL Master 700 has less refractive error, lower percentage of hyperopic shift, and greater clinical advantages IOL Master 700.

Objective:To establish a rapid and accurate method for the detection of Klebsiella pneumoniae carbapenemase (KPC) carbapenemase gene based on recombinase aided amplification (RAA)-CRISPR-Cas13a (CRISPR-Cas13a) technology. Methods:Twenty-five clinical isolates of carbapenem-resistant Klebsiella pneumoniae (CRKP) and five carbapenem-sensitive Klebsiella pneumoniae (CSKP) strains preserved in 2020-2021 in Beijing Chuiyangliu Hospital were randomly collected, and the total DNA samples of the strains was extracted. RAA primers specific for KPC DNA and CRISPR RNA (crRNA) were designed to establish a rapid and accurate method for the detection of KPC carbapenemase gene based on RAA-CRISPR-Cas13a technology. The method was evaluated by plasmids and clinical sample strains, and the detection was also performed by Quantitative real-time PCR (qPCR) method to compare the detection rate and consistency of the two methods. Results:The RAA-CRISPR-Cas13a method can detect KPC plasmids and samples with a sensitivity of 1 copy/μl, which is higher than that of qPCR (10 1 copies/μl). Among the 30 clinical strains (including 25 CRKP strains and 5 CSKP strains), 23 strains were detected to carry KPC gene by both RAA-CRISPR-Cas13a method and qPCR method, and 7 strains were not detected with KPC gene. The detection rate of KPC gene in the 25 CRKP strains was 92% (23/25). The positive coincidence rate of the two methods was 100% (23/23). Conclusions:This study combined RAA amplification technology with CRISPR-Cas13a technology to establish a rapid and accurate method for detecting KPC carbapenemase gene. The method is useful for accurate screening of KPC carbapenemase-producing strains. It has a wide application prospect in drug resistance monitoring and infection control.

Objective To investigate the current situation and health effects of indoor microbial pollution in Xi'an, to analyze the purification effect of air purifiers on indoor microbial pollution, and to provide reference for improving the indoor environment. Methods Through stratified random sampling, 20 families from rural areas and 20 families from upwind and downwind urban areas respectively were selected from Xi'an. Data was collected by questionnaire surveys and on-site environmental sampling. Non-parametric analysis and correlation analysis were used for statistical analysis. Results Overall, the standard-exceeding rate of total count of bacteria was 5.00%. The medians of the total count of bacteria and fungi were 312.50 cfu/m3 and 260.00 cfu/m³, respectively. In terms of health effects, the correlation between rhinitis and cold with total bacterial count was statistically significant (P<0.05), with the correlation coefficients of 0.182 and 0.223, respectively. Purification effect of air purifiers on microbial pollution was statistically significant (P<0.05). After opening for 2 hours, the total numbers of bacteria and fungi decreased significantly. Conclusion The occurrence risk of colds and rhinitis is increased by indoor microbial pollution. Air purifiers have a certain effect on decreasing the total number of bacteria and fungi. It is recommended to use air purifiers with high CADR of particulate matter, double-layer filter and sterilization and dehumidification function, and replace the filters regularly to reduce indoor microbiological contamination.

Objective To investigate the clinical efficacy of modified Banxia Houpu Decoction plus Deanxit for the treatment of cancer-related depression(CRD)of phlegm blended with qi type.Methods Sixty-four CRD patients with phlegm blended with qi type were randomly divided into the treatment group and the control group,with 32 patients in each group.The control group was given oral use of Deanxit,and the treatment group was treated with modified Banxia Houpu Decoction plus Deanxit orally.The course of treatment covered 4 weeks.The changes of Karnofsky Performance Status(KPS)scores,self-rating depression scale(SDS)scores,and traditional Chinese medicine(TCM)syndrome scores in the two groups were observed before and after the treatment.Moreover,the efficacy for improving KPS scores and TCM syndrome efficacy in the two groups were also evaluated.Results(1)After 4 weeks of treatment,the total effective rate for improving KPS scores in the treatment group was 90.63%(29/32),and that in the control group was 78.13%(25/32).The intergroup comparison showed that the efficacy for improving KPS scores in the treatment group was significantly superior to that in the control group(P＜0.01).(2)In terms of the efficacy of TCM syndromes,after 4 weeks of treatment,the total effective rate for improving TCM syndrome scores in the treatment group was 87.50%(28/32),and that in the control group was 40.63%(13/32),and the efficacy of TCM syndromes in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the KPS scores in the treatment group were significantly increased compared with those before treatment(P＜0.05),and the KPS scores in the control group tended to increase compared with those before treatment,but the difference was not statistically significant(P＞0.05).The intergroup comparison showed that the effect on increasing KPS scores in the treatment group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the SDS scores in the two groups were lower than those before treatment(P＜0.05),and the effect on lowering SDS scores in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the TCM syndrome scores of the two groups were lower than those before treatment(P＜0.05),and the effect on lowering TCM syndrome scores in the treatment group was significantly superior to that in the control group(P＜0.05).Conclusion Modified Banxia Houpu Decoction plus Deanxit exerts certain effect for the treatment of CRD of phlegm blended with qi type.The combined therapy can effectively improve the depression mood and quality of life of the patients,and its efficacy is superior to that of Deanxit alone.

BACKGROUND:Our previous experimental results have shown that hyaluronic acid hydrogel can act as a vehicle for bone marrow mesenchymal stem cell delivery to improve the cardiac function of rats with myocardial infarction. OBJECTIVE:To explore the molecular mechanism of bone marrow mesenchymal stem cells and hyaluronic acid hydrogel in promoting damaged heart repair. METHODS:Bone marrow mesenchymal stem cells from male Sprague-Dawley rats were isolated and cultured,and then hyaluronic acid-encapsulated bone marrow mesenchymal stem cells were cultured in vitro in a three-dimensional manner.A model of myocardial infarction was made by ligating the left anterior descending artery of female Sprague-Dawley rats.After 1 week,the model rats were screened by ultrasonic testing and then eligible ones were randomly divided into four groups:PBS group(n=12),hyaluronic acid group(n=12),bone marrow mesenchymal stem cell group(n=15),and hyaluronic acid-encapsulated bone marrow mesenchymal stem cell group(n=15).At 1 week after ligation,the model rats underwent the secondary thoracotomy followed by corresponding injections into the infarcted region and its marginal zone.The expression levels of matrix metalloproteinase-2,vascular endothelial growth factor,thymosin β4 and c-Kit were examined at post-injection day 1,week 1 and week 2 by western blot assay.At post-injection week 2,immunofluorescence staining was used to detect the differentiation of transplanted cells. RESULTS AND CONCLUSION:(1)The expression levels of matrix metalloproteinase-2 and vascular endothelial growth factor protein in the infarct zone in the bone marrow mesenchymal stem cell group were significantly up-regulated at week 1 compared with the other three groups(P<0.05).At week 2,the hyaluronic acid group had a lower expression of matrix metalloproteinase-2 and vascular endothelial growth factor protein than the other three groups(P<0.05).However,the expression of matrix metalloproteinase-2 and vascular endothelial growth factor protein in the hyaluronic acid+bone marrow mesenchymal stem cell group was not significantly different compared with the bone marrow mesenchymal stem cell group.This was primarily attributable to a prolonged paracrine effect via the controlled release of the hyaluronic acid hydrogel.This prolonged paracrine effect offsets the inhibitory effect induced by hyaluronic acid hydrogel at 2 weeks.(2)Compared with the PBS group,thymosin β4 and c-Kit expression levels in the hyaluronic acid group,bone marrow mesenchymal stem cell group and bone marrow mesenchymal stem cell+hyaluronic acid group were significantly increased(P<0.05).(3)No differentiation of transplanted cells into cardiomyocytes or blood vessels was detected 2 weeks after transplantation.(4)It is indicated that transplanted bone marrow mesenchymal stem cells promote myocardial repair through the paracrine effect,and hyaluronic acid hydrogel prolongs the paracrine effect of transplanted bone marrow mesenchymal stem cells.
